CHS strives to provide extraordinary care to patients and the communities it serves. This proposed evaluation is designed to guide CHS strategy and quality improvement by applying research methodology and data analytics to support the environment of a Learning Health System. Ultimately, as CHS deploys resource intensive interventions like the CHS-TS, it is important for the system and its patients to know answers to questions such as: What type of patient does the CHS-TS help?; How much benefit might be expected?; and At what cost?
